Overview

This genuine OEM control board kit (part number 1183618) is the integrated furnace control for the ICP / Tempstar / Heil RGS180SECA0AAAA gas furnace. The control board is the brain of the furnace — it sequences ignition, manages the inducer and blower motors, monitors safety switches and flame sensing, and stores diagnostic fault codes. When the board fails the furnace may not respond to the thermostat, blow cold air, short-cycle, run the blower continuously, or flash error codes on the diagnostic LED. Shipping as a complete kit, this replacement restores full safe operation and proper sequencing of the heating cycle.

Frequently Asked Questions

Does this Control Board fit my ICP RGS180SECA0AAAA — 1183618 | Ships Today?

Yes. This is the factory-specified OEM control board for the ICP RGS180SECA0AAAA — 1183618 | Ships Today. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the control board on my ICP RGS180SECA0AAAA — 1183618 | Ships Today?

Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.

My HVAC system is completely dead. What could be wrong?

Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.

Is this control board compatible with Bryant or Payne too?

Many ICP parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my ICP control board?

OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.

How fast does National HVAC Parts ship?
